To all whom it may concern:

Be it known that I, J OH R. DEAN, a citizen of the United States,.residing at North Girard, in the county-of Erie and State of Pennsylvania, have invented new and useful Improvements in Wire Bending Machines, of which thefollowing is a specification.

This invention relates to wire bending machines and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out inthe claims.

The machine is peculiarly adapted for bending wires into the form of garment stays and as shown is arranged for this purpose.

The invention is illustrated in the accompanying drawings as follows:

Figure 1 shows a front elevation of the machine, partly in section on the lines 11 in Figs. 2 and 3. Fig. 2 a plan view of the machine. Fig. 3a section on the lines 3-3 in Figs. 1 and 2. Fig. 4 a section of a part of the machine on the lines 44 in Figs. 1 and 3. Fig. 5 a central section of the shuttle on the line 5-5 in Fig. 3. Fig; 6 a central section through the flattening rolls on the line 6-6 in Fig. 2. Fig. 7 a fragment of a stay formed of a plurality. of, wires. Fig. 8 a fragment of a stay formed of a single wire.

- 1 marks the base plate of the machine. This is mounted on the legs 2. A guide plate 3 is secured to the base plate by bolts 4. The 'guide plate has .the cut-out portions to form the guide ways 5. The inner edges of the guide ways are formed by the plates 6., The plates 6 are mounted on the shafts-'7 and are secured thereon by means of set screws 8. The shafts 7 extend through the perforations 9 in the posts 10, and are secured in place therein by the set screws 11. The posts 10 are secured to the 'base plate, 1 by the/bolts 12. By adjusting the shaft 7, the plates 6 may be brought into the same plane with the plate 3. The shaft is so located as tobring the plates 6 into such position as to make their edges parallel with the edges of the opening in the guide plate .3 so as to form the guide ways 5.

F oriuing pins 13 are carried b the plates 6 at each side of the crossing an are spaced a distance apart to give the proper width to the fabric. These pins are L-shaped having an outwardly extending portion extending in an axial direction n which the wire is chine is designed formed and ,a laterally extending portio which affords a means for fastening the pins. The lateral portion is clamped on a deflecting plate 14 by means of a clamping plate 13, the clamping plate being secured in place by screws 13". This shape of forming pin is important in. that it is subjected to constant strain and at the same time, the forming pins must be of very small diameter to give the loops of the stay such a diameter as is ordinarily desired.

cured on the plate 6 and by adjusting this plate, the width between the pins 13 may be adjusted. The plate 14 is provided with a slot 14 through which the screw entering the plate 6. An adjustable screw 14 extends through a web 14 on the plate 14 into the plate 6, the screw having the shoulders 14 at each side of the web to lock the screw against axial movement with relation to the web. By loosening the screw 14", and then turning the screw 14, the plate 14 may be moved to any desired position giving the desired posiflion to the pin 13, and then locked in position by tight ening the screw 14".

The deflecting plates 14 have an off-set 15 at the crossing permitting the part of the shuttle 16 on the outer ace 0 the guide plate to pass under it. As shown, the mato form a fabric of three wires, and three shuttles 16, 16 and 16 are shown. The shuttle is shown in detail in Fig.5. It has the two guide plates 17 and 18, the guide plate 17 being arranged on the face of the plate 6 from which the forming pinsextend, and the plate 18 being on the back side of the ide plate. These plates 17 and 18 are of greater width than the guide slot 5 so that the surfaces of the plates 3 and 6. The plates are united by the pins 19, the pin being headed into the plate 17 and secured to the plate 18 by means of the nut 20. This construction permits the removal of the plates and in this manner 'shuttle from the guide way. -Rollers 21 are arranged on the pins 19 and reduce the friction on the surfaces of the guide ways. The frame 23 has the driver stud 24 and this stud is headed at 25 in the plate 18. A roller 22 is arranged on the stud 24. The bobbin 27 has the central opening 28 into which projects a pin 29 fromone end of the frame 23. A spring 30 is arranged at the opposite end. c pin -30 extends The deflecting plate 14 is adjustably seextends a screw 14,

they at all times overlap the removal of the through a capped socket 31 and is provided with a knob 32-at its outer end. A washer 33 is secured to the pin 30 adjacent to its inner end and a spring 34 is arranged between the washer 33 and the end of the capped socket 31 and tends to crowd the pin 30 into the opening 28.

The wire 35 passes from the bobbin 27 through a tube 26, the tube extending through the stud 24 and the plates 18 and 17. The wire passes from the tube to the tension wheel 36. The wire is wrapped aroundthe tension wheel 36 a suflicient number of times ,to prevent any material slipi re 8 coils, the shuttles from .the base ping on the wheel 36. The tension wheel is 'rotatively mounted-on the stud 37, the stud ,bei. g Secured Ito the plate 17 Friction disks 8 8 are arranged each side of the wheel 36, and washers 39 are arrangedat each side .of the'disks38. The the'stud 37 and b means of it, the friction on the tension w eel 36 ;may be controlled to give any tension to the wire desired. The

wire passes from .the tension Wheel between.

thegrooved guide pulleys 41. These guide pulleys are mounted on the pins 41 and the plate 41 extends from one pin 41 to the .other, thus preventing any possibility of the esca e of the wire from between the grooved ,gui pulleys 41.

The-shuttles are .mounted on the guide .Ways with one plate on each face of the plates 3. ,and 6 and are held in place by the '-pins 19. They are forced through the guide Ways by a driving device so as to traverse the figure,8 uide Way and .thus wrap the wire ,alternate y on the pins 13 so as to form fig- ,passing from one v 00p of the guide way to the other through .the space 15 and drawing the wire over; the deflecting plate 14 on to the .pins 13. The loqps are formed at the rear end of the pins 13 and as each loop is formed, it is crowded .in .between the preceding loop and the de fllecting plateat the base of the pin 13. In ,t is .the pins 13, in the ,form of figure 8 coils, the axis of these coils bein lengthwise of the fabric as it is forced o the pins. Where several shuttles are used, as in the machine illustrated, these coils may be interlocked at the; edges as clearly shown in the fabric shown-in Fig.7.; v Asbefore stated, this machine is arranged to form the fabric 43 of three wius as ,shqwn-m Big. 7 and, therefore, has the three shuttles16f, 16 and 16 carrying the wires .42 42 and 42 respectively.

11 order to prevent the outward swinging of the wires and consequent wrappin outside of thebase, of the pins, I provi e the ,guide plates 44 spaced outwardly slightly from the deflecting plates 14. These are mounted on the'bars 45 extending upwardly plate and have the outwardly nut 40 is screwed on to bent 1p 46 so as to assure the ready entry of the wires between the plate 44 and the plate 14. Drivers 47 are provided with the arms 48 in which are arranged the notches 49. The hubs 50 of the drivers are secured on the hubs 51 of the gears 52. The gears 52 are -journaled on the shaft 7 so that the drivers rotate with thisshaft as an axis. The guide ways 5 are circular in form so that the engaging notches 49 traverse approximately the centers of these guide ways. The roller 22 on the shuttles enters the notches 49 on the arms 48, andthe drivers in this way form a driving connection with the shuttles. The two gears 52 ,are in mesh so that the two drivers are kept in constant relation to each other and the arms of the drivers are so arranged with relation to each other that they .reach the crossing of .the guide ways 5 so that the roller 22 is in mesh with the notch 49 in both drivers at the same time so that the guideway, it isen aged by the driver of the receiving loop be from the driver of the discharging loop. This position of. the parts is clearly shown in dotted lines in Fig. 3. In this way, the

shuttles are constantly engaged throughout their travel andat all times are maintained in the exact relation to each other so that the wire is given exactly the right movement and each wire with relation to ,theothers.

One of the bybolts 54. Thegear 55 meshes with a gear 56. The gear 56 1s fixed on the shaft.57 by .means of a set screw 58. The shaft 57 is journaled in bearings 59 extending from the base 1 between the legs 2. The shaft57 is way,.the loops are constantly forced off driven bythe drive pulley 60,.and the drive pulley 60 is driven from any convenient source of power.

As the fabric is forced off the pins 13, the loops have theiraxes longitudinally of the fabric. In order to form it'for use as a garment stay, 7 it so thatthe axes of the loops are practically vat rightangles to the line of the fabric. I .preferto accomplish this by a series of crushing-rolls 62, 63 and 64. These rolls are journaled .on the shafts 65, 66 and 67 respectively, and the journals 65, 66 and 67 are carried in bearings -68, 69 and 70 respectively. These bearings are carried by the frame '71 extending upwardly from the base plate it and secured thereto by bolts 72. One .of the shafts ofeach set of rolls is provided witha beveled gear. The shafts on the mills-62, 63 and 64 have the respectively. Gears 76, 7 and 78 mesh with the gears 73, 74 and 75 respectively mounted on a shaft 7 9. The shaft 79 is mounted in the bearings 80 extending from the frame 71. A sprocket wheel 81 is fixed on the shaft 79 and a chain 82..connects the sprocket wheel 81 with a sprocket wheel 83.

ore it is disconnected gears 52 is secured to a gear 55 it is necessary to crush it or:bendears '73, 74 and as the shuttle is delivered from one loop of The sprocket wheel 83 is fixed on the shaft 57 and in this way, the rolls 62, 63 and 64 are driven.

In order to stretch the fabric so as to give to the loops the relation one to the other desired, it is necessary to provide a stretching device and this preferably operates to stretch the fabric while it is being held by the crushing device, the fabric passing from the crushing rolls between the stretching rolls 84. These rolls are mounted on the shafts 85, and the shafts are carried in the bearings 86. The bearings 86 are mounted in the frame 71. mounted between it and the ratchet wheel 87. A ratchet plate 88 is journaled on the,

same shaft. It carries the ratchet pawls 89 which are forced into engagement by the springs 90. These pawls aremounted on the pins 89 and have a slightly diflerent spacing than the ratchet wheel so that the pawls drop into engagement successively and thus prevent lost motion between the plate and the ratchet wheel. A rocker arm 91 is pivoted on the plate by means of a pin 92. The arm is provided with a stop 93 which limits its movement in one direction and a screw 94 which acts as a stop to limit its movement in the opposite direction. By adjusting the screw 94, the length of free movementof the rocker arm is controlled and consequently the feeding movement may be thus adjusted. A link 95 is connected to the rocker arm by. a pin 96. The link 95 is con nected with the eccentric rod 98 by a pin 97.

The eccentric rod 98 terminates in the eccentric strap 99. The strap is journaled on the eccentric 100 which is mounted on the shaft 57. In this way, the plate 88 is reciprocated with each revolution of the shaft 57 and the stretching rolls 84 are thus rotated. \The.

amount of rotation and consequently, the amount of stretch given to the fabric is controlled by the set screw 94.

It will be noted that the rolls 63 and 64 are of conical shape but on parallel axes. For this reason only the larger ends of the rolls are in contact or operate upon the fabric as it passes through the rolls. It will also be noted that these sets of rolls are ar-. ranged in reverse relation. This form of roll which operates only on one edge at a time is much more effective for some types of fabric, especially the single wire fabric shown in Fig. 8, than the cylindrically shaped rolls-operating upon the entire fabric. These conical rolls will stretch one edge and lay the loops down one after the other effectively where the cylindrical roll would almost entirely fail to effect the result.
